C# |检查两个排序列表对象是否相等

原文:https://www . geeksforgeeks . org/c-sharp-check-if-two-sorted list-objects-equal/

从对象类继承的等于(对象)方法用于检查指定的排序列表对象是否等于另一个排序列表对象。

语法:

public virtual bool Equals (object obj);

这里, obj 是要与当前对象进行比较的对象。

返回值:如果指定对象等于当前对象,则该方法返回,否则返回

以下程序说明了上述方法的使用:

例 1:

// C# program to if a SortedList
// is equal to another SortedList
using System;
using System.Collections;

class Geeks {

    // Main Method
    public static void Main(String[] args)
    {

        // Creating a sorted list of key/value pairs
        SortedList fslist = new SortedList();

        // Adding pairs to fslist
        fslist.Add("Maths ", 98);
        fslist.Add("English ", 99);
        fslist.Add("Physics ", 97);
        fslist.Add("Chemistry", 96);
        fslist.Add("CSE     ", 100);

        // Checking whether fslist is
        // equal to itself or not
        Console.WriteLine(fslist.Equals(fslist));
    }
}

输出:

True

例 2:

// C# program to if a SortedList
// is equal to another SortedList
using System;
using System.Collections;

class Geeks {

    // Main Method
    public static void Main(String[] args)
    {

        // Creating a sorted list of key/value pairs
        SortedList fslist = new SortedList();

        // Adding pairs to fslist
        fslist.Add("Maths ", 98);
        fslist.Add("English ", 99);
        fslist.Add("Physics ", 97);
        fslist.Add("Chemistry", 96);
        fslist.Add("CSE     ", 100);

        // Creating an SortedList
        SortedList fslist2 = new SortedList();

        // Adding elements to SortedList
        fslist2.Add("1", "one");
        fslist2.Add("2", "two");
        fslist2.Add("3", "three");
        fslist2.Add("4", "four");
        fslist2.Add("5", "five");

        // Checking whether fslist is
        // equal to fslist2 or not
        Console.WriteLine(fslist.Equals(fslist2));

        // Creating a sorted list of key/value pairs
        SortedList fslist3 = new SortedList();

        // Assigning fslist2 to fslist3
        fslist3 = fslist2;

        // Checking whether fslist3 is
        // equal to fslist2 or not
        Console.WriteLine(fslist3.Equals(fslist2));    
    }
}

输出:

False
True

注意:如果当前实例是引用类型, Equals(对象)方法检查引用是否相等。
